Not at all, as i said it's really not that complicated, you just run them tthough the side panles in your car. Make sure that you keep the power wires on one side and the others on the other, so you won't have any interferences thus causing engine noise though the speakers. Also, if you'll use an Opus make sure you buy a dedicated automotive wirring set. In the manual it says that it needs a 12AWG wire straight from the battery, with the inline fuse of course, wich shloud be about 15A, but you can go thicker you wish. Not 8 AWG thiker, as the 8 AWG wire id too think to enter inside the Opus power conector.
